.SH SYNOPSIS
.sp
\fBmongos\fP for "MongoDB Shard," is a routing service for
MongoDB shard configurations that processes queries from the
application layer, and determines the location of this data in the
\fIsharded cluster\fP, in order to complete these operations.
From the perspective of the application, a
\fBmongos\fP instance behaves identically to any other MongoDB
instance.
.SH OPTIONS
.SS Core Options
.INDENT 0.0
.TP
.B mongos
.UNINDENT
.INDENT 0.0
.TP
.B \-\-help, \-h
Returns information on \fBmongos\fP options and usage.
.UNINDENT

.TP
.B \-\-version
Returns the \fBmongos\fP release number.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-config <filename>, \-f
Specifies a configuration file for runtime configuration options. The
configuration file is the preferred method for runtime configuration of
\fBmongos\fP\&. The options are equivalent to the command\-line
configuration options. See http://docs.mongodb.org/manual/reference/configuration\-options for
more information.
.sp
Ensure the configuration file uses ASCII encoding. \fBmongos\fP does not
support configuration files with non\-ASCII encoding, including UTF\-8.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-verbose, \-v
Increases the amount of internal reporting returned on standard output
or in log files. Increase the verbosity with the \fB\-v\fP form by
including the option multiple times, (e.g. \fB\-vvvvv\fP\&.)
.UNINDENT
.INDENT 0.0
.TP
.B \-\-quiet
Runs \fBmongos\fP in a quiet mode that attempts to limit the amount of
output. This option suppresses:
.INDENT 7.0
.IP \(bu 2
output from \fIdatabase commands\fP
.IP \(bu 2

.IP \(bu 2

.IP \(bu 2

.UNINDENT
.INDENT 0.0
.TP
.B \-\-port <port>
Specifies the port number when the MongoDB instance is not running on the
standard port of \fB27017\fP\&. You may also specify the port number
using the \fB\-\-host\fP option.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-bind_ip <ip address>
Specifies the IP address that the \fBmongos\fP process binds to and
listens for connections on. By default \fBmongos\fP listens for
connections for all interfaces. You may attach \fBmongos\fP to any
interface. When attaching \fBmongos\fP to a publicly accessible
interface, ensure that you have implemented proper authentication and
firewall restrictions to protect the integrity of your database.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-maxConns <number>
Specifies the maximum number of simultaneous connections that
\fBmongos\fP will accept. This setting will have no effect if the
value of this setting is higher than your operating system\(aqs configured
maximum connection tracking threshold.
.sp
This setting is particularly useful for \fBmongos\fP if you have a
client that creates a number of collections but allows them to timeout
rather than close the collections. When you set \fBmaxConns\fP,
ensure the value is slightly higher than the size of the connection pool
or the total number of connections to prevent erroneous connection
spikes from propagating to the members of a \fIsharded cluster\fP\&.
.sp
Changed in version 2.6: MongoDB removed the upward limit on the \fBmaxConns\fP setting.

.UNINDENT
.INDENT 0.0
.TP
.B \-\-syslog
Sends all logging output to the host\(aqs \fIsyslog\fP system rather
than to standard output or a log file as with \fI\%\-\-logpath\fP\&.
.sp
\fI\%\-\-syslog\fP is not supported on Windows.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-syslogFacility <string>
Specifies the facility level used when logging messages to syslog. The
default is \fBuser\fP\&. The value you specify must be supported by your
operating system\(aqs implementation of syslog. To use this option, you
must enable the \fI\%\-\-syslog\fP option.
.UNINDENT
.INDENT 0.0
.TP
.B \-\-logpath <path>
Specifies the path for the log file that holds all diagnostic
logging information.
.sp
Unless specified, \fBmongos\fP will output all log information
to the standard output. Additionally, unless you also specify
\fI\%\-\-logappend\fP, the logfile will be overwritten when the
process restarts.
.sp
\fBNOTE:\fP

.sp
All \fBmongos\fP instances \fBmust\fP specify the hosts in the

.B \-\-localThreshold
Affects the logic that \fBmongos\fP uses when selecting
\fIreplica set\fP members to pass read operations to from clients.
Specify a value in milliseconds. The default value is \fB15\fP, which
corresponds to the default value in all of the client \fBdrivers\fP\&.
.sp
When \fBmongos\fP receives a request that permits reads to
\fIsecondary\fP members, the \fBmongos\fP will:
.INDENT 7.0
.IP \(bu 2
Find the member of the set with the lowest ping time.
.IP \(bu 2
Construct a list of replica set members that is within a ping time of
15 milliseconds of the nearest suitable member of the set.
.sp
If you specify a value for \fI\%\-\-localThreshold\fP,
\fBmongos\fP will construct the list of replica members that are
within the latency allowed by this value.
.IP \(bu 2
Select a member to read from at random from this list.
.UNINDENT
.sp
The ping time used for a member compared by the
\fI\%\-\-localThreshold\fP setting is a moving average of recent ping
times, calculated at most every 10 seconds. As a result, some queries
may reach members above the threshold until the \fBmongos\fP
recalculates the average.

documentation for more information.

.B \-\-chunkSize <value>
Determines the size in megabytes of each \fIchunk\fP in the
\fIsharded cluster\fP\&. The default value is 64 megabytes, which is the
ideal size for chunks in most deployments: larger chunk size can lead to
uneven data distribution; smaller chunk size can lead to inefficient
movement of chunks between nodes. However, in some circumstances it may
be necessary to set a different chunk size.
.sp
This option \fIonly\fP affects chunk size when you initialize the cluster
for the first time. If you later modify the option, the new value has no
effect. See the http://docs.mongodb.org/manual/tutorial/modify\-chunk\-size\-in\-sharded\-cluster
procedure if you need to change the chunk size on an existing sharded
cluster.

.TP
.B \-\-noAutoSplit
Prevents \fBmongos\fP from automatically inserting metadata splits
in a \fIsharded collection\fP\&. If set on all
\fBmongos\fP instances, this prevents MongoDB from creating new
chunks as the data in a collection grows.
.sp
Because any \fBmongos\fP in a cluster can create a split, to
totally disable splitting in a cluster you must set
\fI\%\-\-noAutoSplit\fP on all \fBmongos\fP\&.
.sp
\fBWARNING:\fP
